97 Grand Prix 3100 Vacuum Help Needed

[95oldsVan]

We bought a 97 GP Se with the 3100 and on the back of the intake manifold,it was missing the vacuum line thats found on the top of the plenum,passenger side.I found another broken vacuum line hanging down under the carat the back of the engine,But also found another broken vacuum line coming up where the washer fluid tank is.Is there supposed to be a T fitting or check valve to connect these 2 lines to the back of the manifold?

 

There was a problem with the a/c not blowing out the correct vents as well...Im familair with these problems on other GM cars but this is new to me with this engine.The broken vacauum line in back of the engine looks like it goes inside a wire harness or somewhere back there...hope this helps explain it a bit.Sorry cant take pics of the stuff.Just need to figure out what goes where.

Thanks.
